amortentia - the most powerful love potion in the world. it smells different to each person, according to what attracts them
“what does your amortentia smell like, minho?”
changbin dropped onto the couch beside him, a green tie knotted around his head. minho thought he looked stupider than ever, which was impressive considering the competition. the younger boys had a habit of mimicking whatever he did, and minho could spot more than five in the room wearing their ties the same way purely because of seo changbin’s influence.
the slytherin common room was vibrating with triumph after their merciless quidditch win over gryffindor this evening. the celebration had already dissolved into rounds of illicit firewhisky and music loud enough to rattle the stone. they didn’t usually bother with this level of noise. but how could they not celebrate when the griffindorks lost against them?
minho slouched back on the couch, one arm draped over the velvet spine. he gave his glass a slow swirl, watching the shadows fracture through the amber liquid.
“burnt caramel. catnip. and something like a girl’s perfume,” he said at last, voice flat. “makes my fucking head spin.”
changbin whistled. “you’ve got it bad. don’t even know who for?”
“didn’t say that.” the corner of minho’s mouth lifted.
changbin leaned back beside minho with a smug smile, tugging his tie further down over one brow like a bandana, as if that somehow made him look less ridiculous. it didn’t.
“it’s y/n, innit?”
minho scoffed. “as if.”
changbin laughed. “please. everyone knows you two aren’t sneaking alone just to duel.”
minho rolled his eyes and took a slow sip of firewhisky, letting the burn settle under his tongue. he didn’t deny it. what would be the point?
and then, as if right on cue:
“speak of the devil.” changbin sat up straighter, snickering.
minho’s head snapped toward where changbin was looking, like a compass needle finding north.
you were across the room, walking away from whoever you’d been talking to, still facing them as you chattered on. your backwards steps were carrying you straight toward the couch where minho and changbin sat. minho was already bracing for whatever stupid, trivial thing you were about to bother him with. he was also looking forward to it.
you laughed brightly, tossing a quick goodbye over your shoulder without really looking where you were going. your shoulders turned first, your head following a second later. your gaze finally landed on minho.
you smiled. minho watched it happen, how it started in your eyes and curled around your pink lips.
he didn’t mean to look lower. truly. but his eyes snagged on the green-striped tie dangling loose and crooked around your neck. the top buttons of your blouse were undone—two, exactly—which made it worse than if you were fully exposed. you weren’t even showing cleavage and he was starting to feel himself sweating. what the fuck was wrong with him?
“hi,” you said, voice sweet as honey but clearly laced with mischief.
minho’s eyes narrowed.
he didn’t trust that smile. but he did want to see what it was about. “what’s going on in that scheming little head of yours?”
your gaze dropped meaningfully to minho’s lap, then lifted back to his face like you hadn't just sent a spark up his spine with one look.
without breaking eye contact, you stepped forward and held out your hand.
“come see,” you said.
minho stared at you for another second. he tilted his head, as a show of resistance. he only did it to keep up appearances and pretend he wasn’t that easy when it came to you. because changbin, smug little bastard that he was, would never let him live it down.
but really, what was the point?
changbin had been teasing him into oblivion for weeks already. so he didn’t bother fighting it now. especially not when you were looking at him like that.
he reached out and took your hand.
changbin gave a low, obnoxious whistle. you gave changbin a little pout over your shoulder, before turning and tugging minho with you. minho let out a soft, helpless chuckle, not even trying to mask how amused he was by your theatrics.
he stumbled a bit as he stood, his balance just off from the alcohol buzzing through his veins, but your grip kept him steady. his laughter followed as you pulled him toward the stairs. he turned around and mouthed help to changbin, who just shook his head.
the noise dulled behind you both as the winding stairs took you higher into the boys’ dorm tower, torches flickering emerald flames in brackets along the wall.
“where are we going?” he asked, breathless more from you than the climb. his voice dropped half an octave.
you didn’t answer him.
still, minho followed without resisting, boots thudding behind yours, his other hand brushing the worn stone railing with each step.
you reached the top and without hesitation, shouldered open the heavy wooden door to the boys’ dormitory.
to your luck, it was empty. the four other boys in minho’s dorm were still all down there, drunk on victory. minho stepped inside behind you, scanning the shadows of his bed’s green velvet hangings, the cracked window open just a little to let in the frigid night air.
“sit,” you ordered, and shoved him.
he fell back onto the bed with a rustle of green and silver sheets, his elbows catching him halfway. his green slytherin tie hung limp around his neck, the collar buttoned neatly.
minho’s heart pounded in his ears. this is it, he thought. you were losing your virginities to each other today.
“you know,” he said, trying to lace his nerves in nonchalance, “if you were ready, you could’ve just said so. we could have a mature, adult conversation about it, instead of—” he gestured at himself, “forcing me into bed like a hostage.”
you gave him a drunk smile. “are you really dense enough to think i brought you up here to shag?”
before he could say anything, you started to climb on top of him, knees bracketing his thighs, your skirt pooling over his lap.
“excuse me if the situation’s a bit confusing,” he hissed, hands planted behind him on the bed. “but you throw me on a bed and you’re climbing on top of me. i don’t know what the hell you expect me to think.”
“oh, i don’t know,” you said, rolling your eyes. “maybe think with your brain instead of your dick for once?”
minho scoffed sharply. his fingers twitched behind him, visibly debating whether to touch you or keep pretending he had a shred of self-control left.
“so,” he murmured. “why’d you drag me here? did you just want to kiss me or what?”
you then slowly reached into the inner pocket of your robe that was laying at the foot of the bed and pulled out two small vials. the pink liquid inside shimmered under the moonlight coming from the window.
the second he saw them, minho stilled under you completely.
“what is that?” his eyes narrowed at the vials.
“come on, minho. use your head.” you watched him, waiting for the penny to drop.
“…love potion?”
you grinned. “from the storeroom. i stole a couple this morning.”
“fucking hell.” he dropped his head back with a groan.
“it’s only temporary,” you said quickly. “i mean, what better way to spend a night than getting high on each other?”
minho stared at the vial, eyes flicking between the slow swirl of pink liquid and the smile playing on your lips like this was the best idea you’d ever had.
“this is fucking stupid,” he said flatly. “absolutely mental.”
he sat all the way up now, forcing you to shift with him, your knees tightening around his hips for balance. he glared at you, jaw clenched, that familiar venom in his stare—but it never really landed when it was aimed at you.
“we will fuck if we drink that.”
“we won’t,” you said smoothly. “we might just see how bad we want to.”
“and that’ll have the exact same outcome,” he snapped. “you have any idea what you do to me already?”
you tilted your head. “then i guess i’m the only one with self-control, here.”
he scoffed, eyes flashing. “you want to talk about self-control? you nearly came just from me kissing your neck in the closet last week.”
“you were moaning and biting my neck,” you snapped back immediately. “who wouldn’t feel turned on?”
“you were the one humping me like a dog. any guy would moan.” he narrowed his eyes. “and i was biting you to shut you up,”
“i was only grinding on you to shut you up!”
“you always grind on me!” he snapped.
you blinked at him, then let out a long sigh, now confused by both of your lines of reasoning. arguing with him always took an unnecessarily large amount of energy. ultimately, you held out the vial.
minho didn’t take it right away. you saw the gears turn in his head. slowly, he reached out and took the glass from your hand.
“fine, i’ll do it. but i have to remind you one last time that this is a horrible idea,” he said, eyes narrowed, voice flat. “monumentally, astronomically stupid. if i wake up in azkaban, it’s on you.”
you grinned so wide your nose crinkled. “i’ll send you letters.”
you uncorked your vial with a soft pop, the shimmer inside glowing faintly. you held your arm out. he shook his head with a huff, uncorking his, and looped his arm through yours.
“bottoms up.”
“cheers,” he mumbled, and you both tipped the vial back.
the potion slid warm and syrupy over your tongue. it was shockingly sweet at first, then spicy underneath which must have been from the peppermint. it burned just a little as you swallowed, fizzing down your throat.
you set the empty vial gently on the bedside table, glass clinking softly against the other.
you both sat there in silence after. nothing happened. no sudden rush of heat or collapsing into each other in a frenzy like people always warned about.
you glanced down at him. his eyes flickered up to yours, one eyebrow raised under his messy bangs.
“i don’t feel anything,” you said finally, frowning.
minho shook his head. “not sure i do either.”
you squinted at him. “do you feel like kissing me until your mouth hurts?”
“always.” his expression didn’t shift. “that’s not the potion,”
you frowned deeper, brows tugging together as you slumped a little. “it didn’t work,” you muttered, lower lip jutting out.
“shame,” he said blandly. “oh well.”
you stared at him, aghast. “oh well?”
minho just blinked at you.
you shoved his shoulder. “you’re unbelievable.”
he barely rocked from the push. “i mean, what did you expect?”
“i expected you to lose your goddamn mind, minho!” you snapped, flinging your arms out in exasperation. “i expected panting, grabbing, throwing me down like some lust-crazed—something.”
“you act like i wouldn’t just do that,” he said.
“i-i expected you to look like you wanted me instead of blinking like the dead-eyed minister!”
minho tilted his head at you, utterly dry. “well, maybe try a bit harder convincing yourself i don’t want you because my cock’s not exactly subtle about it.”
you froze for a beat. your eyes dropped before you could stop them, dragging down his front. at his crotch, the fabric of his trousers was dark and creased.
minho was still propped on his elbows, watching you with infuriating neutrality. he made no move to help or hide anything.
you blinked up at him. “could just be a wrinkle,” you muttered.
he smirked. “could be. wanna check?”
you glared. as if the potion failing wasn’t irritating enough, minho’s smug little remarks were the last thing you needed.
“what a pathetic waste of time,” you huffed, glaring at the empty vials on the bedside table. “excuse for a love potion, honestly. we could have been making out this entire time instead of sitting around.”
minho’s mouth curled, equal parts amused and relieved. “i second that,” he said.
before you could respond, he grabbed you by the collar and pulled you into a heated kiss.
you let out a startled gasp but the shock melted instantly. you could’ve sworn you felt your pulse in places it had no business being. it was stupid, how fast your body went from annoyed and bickering to suddenly grinding down without even thinking, chasing friction because your brain had long since checked out.
minho pulled back. “bloody hell,” he rasped as you rolled your hips again. “i think i’m gonna die.”
you couldn’t help but giggle quietly. “i should hope not. you’re far too useful to have around, especially when you kiss me like that,” you teased.
he grinned, the expression soft. “that’s all i am to you, y/n? something useful?” his fingers brushed your cheek, trailing down your jaw, thumb catching on your bottom lip.
“well, you’re more than a little fit. and apparently good at snogging.”
minho had never felt so at ease flirting with you. it felt as if his natural defences melted into nothing. he should have been wondering if it was the love potion starting to take effect, but honestly, he’d forgotten about that already. it was hard to care about enchanted syrup when you were giggling against his lips. he had tunnel vision. his world was reduced to you and the little creases beside your eyes when you smiled at him.
he leaned in, letting his nose brush yours, voice pitched just for you. “i’ll have you know, i’m exceptional at a few things besides snogging. if you’re lucky, i might demonstrate.”
you grinned. “well, i am the luckiest girl in the world, aren’t i?”
minho let out a chuckle as your noses nudged together. then he kissed you softly. you sighed against his mouth, melting into the kiss, your arms hugging his neck.
his hand drifted up the bare skin of your thigh, fingertips tracing lazy circles higher, slipping beneath your skirt. his fingers splayed to cup your ass, and you let out a muffled moan into his mouth. your lips left his, trailing down to the line of his jaw, then to his neck. you sucked at his skin, your tongue flicking out to soothe the mark after. he tilted his head back to give you more space, hands gripping you tighter as you painted little love bites in the area below his ear.
you broke away, your mouth hovering above his, lips still brushing as you caught your breath. “minho,” you murmured.
he hummed, eyes half-lidded. “what is it?”
you took another little breath, heart thudding wild in your chest. “we’ve never really…well, brought each other off before.” you smiled, gaze flicking up to meet his. “thought maybe you’d want to try something more tonight.”
he stilled, then his mouth curled at the corner. “you want me to make you come?”
you nodded. “i mean, i’ve only ever done it myself, when the dormitory’s empty.”
“well,” he murmured, “who do you think about when you’re alone?”
you rolled your eyes, fighting a smile. “that’s private, minho.”
he grinned, not the least bit chastened. “wouldn’t be uncomfortable if you said it was me, that’s all.”
you pressed a quick, warm kiss to his jaw, lips curving against his skin. “who else would it be, you idiot?” you whispered.
minho’s smile stretched wide, his eyes shining with an affection that made your chest flutter. his hand slid from your ass around to the front, fingertips dancing along the edge of your knickers, only your skirt hiding you. he paused there, eyes flicking up to yours, his voice a low murmur just for you. “you’re alright with this?” he asked.
“yes,” you breathed, hardly more than a whisper.
his fingers slipped near the thin cotton. you buried your face in the curve of his neck, your breath shuddering against his skin.
minho thought maybe he’d spoken too soon about the potion not working, because he felt utterly, pathetically besotted. he’d loved you for years, but right now he wanted you to know it.
“i think i’m in love with you,” he whispered.
you grinned against his skin. “i think so too.”
“in love with me, or you also think i’m in love with you?”
“i don’t know, i think both,” you whispered, “you’re being very distracting.”
minho had only just started to reach down, fingers barely sliding under your panties, when the heavy door burst open with a bang against the stone wall. minho’s hand instantly yanked back, your body scrambling off his lap, straightening your skirt as you tried desperately to look like you hadn’t just been caught on the precipice of something indecent.
standing in the doorway was bang chan, the ever-diligent slytherin head boy. his gaze swept over the two of you, lingering on your flushed faces and disheveled uniforms.
“i knew you two were up here!” chan bit out. “thank goodness i caught you before something actually happened.”
minho’s jaw clenched, irritation flaring in his eyes as he shifted to sit a little straighter on the bed, deliberately casual. “do you mind?” he shot back.
“yes, actually, i do mind,” chan replied coldly, marching further into the room. he fixed you with a hard stare, eyes narrowed. “y/n, you stole two vials of love potion from the storeroom this morning you think no one would notice?”
your heart leapt into your throat, hands twisting in your skirt, trying desperately not to meet chan’s eyes for fear you’d laugh.
minho rolled his eyes, utterly unrepentant. “nothing even happened, chan. you’re interrupting a perfectly innocent evening.”
chan snorted, gaze flicking between you and the empty vials on the bedside table. “innocent? this is the stupidest shit i’ve ever seen—consuming potions so you can be in the completely wrong state of mind—merlin’s beard, this is exactly how people end up with a howler from your parents or, i don’t know, bloody pregnant! ”
he stepped forward and snatched the vials, shoving them deep into his robe pocket. you and minho watched in silence, equal parts shame and irritation burning in your chests. all you wanted was chan out of the room so you could pick up where you’d left off.
“y/n, you’re coming with me. minho, stay put.”
you reached for minho’s hand immediately, a frown washing over your features. “i’m not leaving him, chan,” you said.
“you’ll have to hex me to take her away.” minho squeezed your hand, looking more sure of himself than ever.
chan stared at the pair of you, then let out a loud sigh and scrubbed his face with both hands. “do you even hear yourselves?”
you barely had time to blink before he was striding forward and grabbing your arm as he pulled you upright off minho’s bed.
“no!” you snapped, trying to twist out of his grip, but he just re-anchored his hold higher on your sleeve and kept moving.
minho’s eyes flared. “you’re the worst fucking head boy in the history of hogwarts—”
“i love you minho,” you cried as you were being dragged towards the exit.
chan finally yanked the door open, muttering under his breath as he tugged you out into the corridor.
when you stepped into the great hall the next morning, it seemed that the two opposing quidditch teams had spent very different nights.
the gryffindor table looked like a funeral procession in scarlet and gold. their players sat scattered and sulking. no one met anyone else’s eyes. the usual boisterous laughter was replaced by silence. it was broken only when some poor guy knocked over a pitcher of pumpkin juice. he let spill across the table for a full three seconds before a passing ghost finally tutted in disapproval.
the slytherins were late. but not all of them. a few had trickled in before you, those that had ducked out early or avoided the worst of last night’s victory bender. changbin was at the table, lounging with his head cradled in both hands like it might fall off otherwise. the same tie he used as a headband last was now around his neck, but loosely knotted and trailing into his plate.
you and your roommates entered, steps slowing as you neared your usual spot.
minho was already there.
he was resting his chin on his hand, elbow propped on the table. his fingers tapped lightly against the side of his face, rhythm distracted, like he wasn’t even aware of it.
you saw the smallest flicker of his eyes the moment your shadow passed into the space across from him. you slid into your seat quietly and some of your roommates settled in beside you. you don’t remember ever feeling this awkward with minho.
you cleared your throat gently.
“hi,” he said.
“hi.”
he glanced down at his own empty plate, then back up. “you… sleep okay?”
“yeah.” you nodded, eyes flicking down. “did chan give you detention?”
he shook his head, “he told me to never let this out or the three of us would all both be doomed.”
“well, that’s good.” you said, staring at the tea in front of you. the steam had thinned, barely curling now, but it gave you something to focus on.
you risked a quick look at him. there was the faintest shadow of a purple mark peeking just above the collar of his shirt. heat crept up your neck at the memory, and you quickly dropped your gaze back to the table.
minho cleared his throat. “did he make you drink the antidote as well?”
you nodded, still not quite looking at him. “last night.”
“gross, wasn’t it?” minho muttered.
“yeah,” you agreed. “absolutely vile.”
one of your roommates, who had been quietly buttering her toast beside you, suddenly perked up.
“antidote?” she asked, eyes widening with curiosity. “antidote for what?”
you froze. minho’s tapping stopped.
minho gave the witch a sharp look. “nothing that concerns you.”
before you could even shoot him a warning glare, changbin’s voice cut through the table.
“antidote for the love potions they took together last night,” he announced. “i heard these two idiots thought it was a brilliant idea.”
“seo changbin!” you hissed, cheeks burning. looks like bang chan wasn't too careful about this secret either.
your roommate gasped, toast halfway to her mouth. “you two—?”
minho’s eyes narrowed at changbin. “if you wanna win the house cup this year, i suggest you zip it. unless you’d rather explain to the entire house why our points suddenly vanished because of your big mouth.”
changbin grinned around a mouthful of eggs, completely unfazed by the threat. “relax. i’m just saying, you two don’t even need potions to be infatuated with each other.”
you pushed your plate away. “i’ve lost my appetite.”
“so have i,” minho said, rising from the bench.
you both stood at the same time, slipping out from opposite sides of the long slytherin table. the green and silver banners swayed overhead as you walked toward the grand doors.
your eyes met minho’s across the aisle. minho tilted his head to the left, referring to the broom closet on that side of the great hall. you scoffed but nodded.
as the two of you left together, changbin muttered under his breath, “there they go again…”
